New Larger TVs Favor LCD Over Plasma 211

Posted by Zonk
from the shiny-writ-large dept.
Information Week is carrying a Reuters story examining the shift towards LCD technology in recent large-screen television models. Though some analysts acknowledge that plasma displays have faster response times over large surfaces, the industry seems to be betting that consumers will prefer higher resolution images over time. From the article: "CPT's Wu agrees that plasma panels, especially 50-inch and larger ones, do excel LCDs in some aspects of picture quality, but he says the sheer size of the LCD camp will help LCD panels overcome whatever drawbacks they have in a timely manner ...With the 40-inch-class market gradually taken over by LCD TVs, plasma models need to migrate to the market for 50-inch TVs and above, but demand is not as well developed there, analysts say. 'The United States accounts for more than 70 percent of demand for 50-inch plasma TVs and larger. In other words, there is virtually no 50-inch-class plasma TV market outside the United States,' DisplaySearch director Hisakazu Torii said."

    It may not be a factor in the US market, but here in Europe plasma's have a bad reputation because of their energy consumption.
    Household equipment is rated in the shops on an energy efficiency scale, and LCD screens score much better than plasma.

    Furthermore, plasma has a tendency to burn in. Of course every manufacturer and salesman will tell you that "this is no longer true", but once the problem has happened they are not so firm in their statements anymore.
    This causes trouble when watching 4:3 transmissions in true 4:3 format (rather than stretched to 16:9).
    It also sometimes causes station logos or newstickers to burn in.
    • by Angostura (703910)
      As I understand it, the problem with comparing plasma and LCD energy ratings is that LCD's power consumption is independent on the image displayed, whereas plasma's consumption varies with the brightness of the image.

      Manufacturers such as Panasonic claim that under normal conditions consumption is about the same. I simply don't know. But I suppose plasma's figures could look unfairly bad if consumption figures are calculated while the TVs are displaying a bright standard test pattern or set of colour bars

      The reason LCDs are outselling plasma displays is mainly that they are sold in brightly lit stores, where you won't easily see the enormous difference in contrast ratio. On the contrary, LCDs are fabricated to look black in direct lighting, while plasmas sometimes tend to look greyish.

      Good stores should have dampened lighting in the TV dept. Plasmas are like projectors, you don't really see what they are capable of in bright light. Turn the lights down on an LCD, and you will see the disastrously poor contrast of LCD technology manifesting itself as glaring, grey areas that are supposed to represent black.

      The other reason is that LCD are preadjusted to do a lot of clipping in white and black areas (which people don't always easily react to) to make the picture look less washed-out. If you correctly calibrate an LCD you will see this limitation quickly.

      To further fool the customers, LCD vendors have a fantast-number called "dynamic contrast", which represents total contrast after frame-by-frame contrast distribution. It would be OK giving ut this specification, had they not omitted the real number. After all, "dynamic contrast 8000:1!" doesn't sound less cool than "contrast 5000:1". It's dynamic, like Batman & Robin. Too bad the real contrast is 1200:1.

      So sure, LCDs may be better for use with a computer, but that is not the reason why they are winning the battles in the elecronics stores.

    I'm not very much of a television watcher, but I do sometimes have friends over to watch movies and such. I recently picked up a projector, and now have a 100ish" display that becomes a blank wall when I'm not using it.

    I'm pretty happy with it, projectors are hardly a specialty item any more, and I doubt it was significantly more expensive than a 50" plasma or lcd television. So I'm having a hard time seeing why anyone who wants a big display would ever purchase anything other than a projector.

      Most people don't have a spare wall to use as a TV screen. Besides, many people don't have the space for a projector. You need to have nothing between the projector and the wall, which is difficult to realize in a small room.
      • And to get the best out of a projector you need a screen (which means the "blank wall" thing goes out of the window) and lower light levels than an LCD or flatscreen - which means curtains during the day or watching at night.

        I find your comment puzzling. I live in Japan and many of my friends have projectors because their apartments are too small to be able to fit even a modest sized television. With a projector they can have a large screen while taking up very little space. Newer LCD projectors are no bigger than a regular sized laptop and fit easily on a shelf or projector mount. Add to this a screen that you can hang from the ceiling on some hooks, and you can get a 50" TV in a tiny space.

          I think he's thinking of the old front projection systems from the 1980s. They had a coffee table sized console that was placed maybe 2m from a large, rigid screen. The screen had to be rigid because it was curved to compensate for off axis optical distortion. Placing the system far enough away from the screen to avoid optical problems would have defeated the purpose of the large screen: you can't sit in front of the projector without blocking the picture.

      First you have contrast ratio. Unless you keep the display compleately dark, a black screen isn't really black. Normal lighting sources boost the dark areas and destroy contrast and to a lesser extent color balance. You can get around this by keeping the room compleately dark, but thats not really practical.

      Is there something here I'm missing?

      There are a number of reasons why people don't want or can't use front projection.

      • Not enough room. You need to have a sizeable room for front projection if you really want to get to that 100" size. Being able to project the image is only part of the equation. Optimal viewing distance for a 50" set is between 6 and 10 feet (depending on HD or SD content). Do you really have a room big enough to accomodate a 20ft viewing distance for your 100" image?
      • Not enough control over ambient lighting. Front projection needs a relatively dark room, much moreso than a rear-projection TV (CRT, LCoS, DLP, LCD) or direct-view (CRT, LCD, Plasma).
      • Wife-acceptance factor. Try telling your wife that she has to make sure the blackout shades are down if she wants to watch her soaps or Oprah in the middle of the day.
      • You realize that size isn't everything. Sure, you can get a 100" display, but depending on the technology in your projector you'll likely suffer screen-dooring or pixelization (especially for low-end consumer-grade projectors). 1280x720 (16x9 720p) at 100" diagonal is 14 pixels per inch.
      • You realize that the price of the projector isn't everything. For proper viewing, you really need a good screen. A flat, white wall is merely "okay". A flat wall with special paint is better. A proper screen is best. Bear in mind that most people don't have truly flat walls, since drywall is usually somewhat textured. It might look flat, but project an image on it and you've suddenly got a bunch of little bumps causing little shadows all throughout the picture. A screen is really the way to go, and that's not cheap, especially if you want a roll-up model so it hides easily.
      When all of the variables are right, front-projection is nice. Getting everything to come together for a proper viewing experience either requires extreme luck or large amounts of money. You can certainly go overboard, like a friend of mine who just put in a $15,000 theater, but even a modest projector + screen + blackout curtains will run you more than the $2000 I spent on a 50" rear-projection DLP.

            It is true that DLP projectors have the same issue with lamp life. The article was comparing plasma and LCD which is why I didn't mention DLP sets. Both my laptops are older than 3 years old and get more than 3 hours of use per day. Neither has required a lamp replacement. The 1500 to 3K hour life of a high intensity projector bulb is considerably shorter than a typical cold cathode lamp in an LCD set.

      > big display would ever purchase anything other than a projector.

      Because most people also use their TVs in the DAY or with lights on and projectors are absolutely crap in the daytime. The contrast ratio falls to next to nothing if there's any light in the room whatsoever.

      The darkest black a projector can display is the black that you see when you look at a WHITE wall. Look at a nearby white wall NOW and decide for yourself if that's an acceptable BLACK level. If LCDs or Plasmas had a black level that bad, NOBODY would buy them and we'd all still be using CRT screens. The ONLY advantage of a projector is it's picture size, but the vast majority of people aren't prepared to cope with all the drawbacks just to get a bigger (washed out) picture.

      Also, projectors are very difficult to site in the average living room. They need to go at the opposite end of the room to all your AV kit and preferably high up on a wall or ceiling. You either have to move all your AV kit to the back of the room and fire your remote controls backwards, or run a signal cable the whole distance of your living room to feed the projector.

      They're great if all you want is a big picture in cinema-like blackout conditions, but they're hardly practical for the average family who needs to install it in a room with windows.

        1) Turn the brightness down. Many projectors have a half-brightness mode, usually named after one of the other benefits of not running full-blast (long-life, whisper-quiet, etc.). Use that mode and you'll have no problem seeing the picture during the daytime.

      DLP has the following limitations:

      1. It is inherently a projector technology, which means:

      a. For a front projection situation, DLP image quality is directly dependent upon the illumination within the room and the screen.

      b. For a rear projection situation (i.e. the one that looks like a stand-alone TV), DLP requires a screen that has inherently poor viewing angles, particularly when viewed above or below the vertical screen limits. Even older LCDs without the "180 degree" viewing angle are far better than any DLP RPTV screen.

      2. It is a technology dependent upon light sources that (currently) have inherently poor lifetimes. Lamps are expensive replacements. When LEDs and lasers come more into the fold, this should alleviate this problem.

      (Note: this could also be construed as an advantage since you'd have all new luminance and you can't replace the CCFL backlight in an LCD which has a tendency to degrade unevenly over time).

      3. It is a technology that, unless you use three separate DLP chips for the primary colors, will be prone to rainbow effects. Even in the 3DLP setups, convergence can also become an issue.

      DLP is good for certain applications but will never be the primary volume driver of the market. Two years ago, it was the only way to get a decent screen size for HD, but not any more. The whole industry has dogpiled onto LCD direct-view, and it'll only get cheaper from here.

      Not really, it makes sense.

      Note that he talks of MARKET, not sales.

      Yes, there are 30% sold outside the US, but this in MANY countries. That means in many markets, which would have to get distinct marketing. in each country, sales are possbily to small individually to talk of a "market". Together, they are nice - but then, this is not ONE market.

      The rest of the world has 20 times as many people as America, yet only 40% of the 50" plasma TV demand. This means America has over 46 times the demand than outside America. I'd say that counts as virtually nothing.
  • I use my plasma TV for two things: Watching DVDs and watching sport. It is while watching sport that the faster response time comes into play. Although I love the higher res of LCD I've yet to see an LCD TV where you can watch cricket on without the ball becoming streak.

    I'm sure there are some US Slashdotters who have the same experience with sports like baseball.
  • I'll be standing over here, with either a highly compacted form of the DIY LCD projector (I'm working on making it near laptop-sized and dealing with heat issues) from Tom's Hardware, or I'm gonna be standing next to that Laser television with a big grin on my face as I pull resolutions higher than the meager 1366x768 most LCD screens come with, far better color gamut, and with no burn-in like a plasma.

      There are quite a few 42" LCD's with 1920*1080 resolution on the market today. They generally have ~8ms response times and can be had as cheap as $1,300 for monitor only models or ~$1,600 for ones with integrated tuners. Other than a PC you aren't going to currently find any source material with more resolution than 1080p so there's little point to having more. Heck even the digital cinema projectors are only 2048x1080 and they project onto a >20m wide screen!

    The problem is sharpness rather than slow updates.

    I just bought a 42" HDTV capable plasma, and had to turn the sharpness down to 50%, as otherwise all non-HDTV contents, including DVD's looked extremely blocky and I could see the MPEG artifacts everywhere - the default image was far too clear. I shudder at the thought of how horrendous it would have looked on an LCD screen, as I usually notice the pixelation far easier on LCD screens than I do on plasmas.

    Maybe I'll consider an LCD screen when I'm using all HD content, or if they start supporting adaptively blurring lower resolution content sufficiently.

    Sharp images only works for me when the DPI of the source is high enough that you can't see individual pixels at normal viewing distances.

    Yes, I realize that means that I've on purpose chosen a screen with a "lower" picture quality, but the end result is far better with 90%+ of the content available to me. And it was cheap enough to replace in a couple of years if a usable LCD screen (or other tech) comes along.

      Maybe the problem is that you're sitting too close to your television?

      I believe the ideal distance to sit from a TV was between 6 and 8 times the diagonal. For your 42" set that's roughly 6 to 8m.

      If, for example, you're sitting 4m from the TV (a common distance in a living room in an appartment), it's not that surprising that you see the pixels on the image.

      That sharpness is not a nice, crisp, clear image, but artificial edge enhancement. The fact that it looks hideous with the sharpness up is not a fault of your plasma; it's the case with LCD and even CRT as well.

      If anything, I've got too much softness by default on my LCD; I've been using the upscaler in the XBox 360 for DVDs instead, to avoid it.

    OK, when WILL plasma tv's offer 1920i resolution? (LCD's have it now)

    When will LCD's offer 10000:1 contrast ratio (IE: good blacks). Plasma has it now.
    When will LCD's be made in 50" screen sizes at prices under $2000-$2500 (can get a plasma in this size
    and price now).

    I currently have a 40" direct view tube tv and will be looking to replace it with a HiDef in the

    This discussion mirrors an article [ieee.org] that appears in the current issue of the IEEE Spectrum magazine [ieee.org]. They review the pros and cons of LCD and Plasma technologies, with a brief look at DLP, SED, LCOS.

    Their take on it? It won't be settled for another couple of years, and there will be two distinct categories: screens below 50" (or 42"), and screens larger. LCD will dominate the smaller screen size market, though SED may replace that when the cost comes down (after 2010?). For larger screens, don't discount projection technology, particularly in terms of cost.

    Incidentally, the cover article [ieee.org] for this issue is on Blake Ross [wikipedia.org], whom they call the Firefox Kid.

    As a member of IEEE, I have read about plasma and LCD in a recent article appeared on Spectrum (I read it on the print edition, but I think the online version [ieee.org] is similar if not the same). The article confirmed what we all know: Plasma is impractical; Long live LCD! The winning technology must be cheap, reliable, with a long lifespan. LCD has all of these characteristics, but Plasma has none of them.
